THROAT FOR BOTTLING MACHINES.

Application filed August 14, 1922. SerialNo. 581,729.

To all whom it may concern:

Be it known that I, O'r'ro PAEPRER, J r., a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Threats for Bottling Machines; and I do declare the following to be a full, clear, and exact de-' scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to throat pieces of bottling machines which crimp metalcap or crowns on the tops of bottles.

In machines of this character, the throat piece engages and compresses the crimped edge of the bottle cap and it soon becomes worn and unfit for use notwithstanding the fact that the bushing or lining of the throat iece is made of the hardest metal obtainable. It therefore becomes necessary'to re-' new the bushings or the entire throat pieces.

In connection with throats now in use, it has been found that they are very expensive. One type now in use has the cap crimping bushing firmly anchored in the body portion or ring and when the bushing has become worn so that it will not properly crimp the bottle caps, it is necessary to return the throats to the factory where special machinery is employed to remove the bushings and put new ones in place. This causes expense and further causes delay due to the fact that the bushings cannot be removed and put in place at the point where the bottling machine is in use.

Another type which is now in use provides a body in the form of a ring having a flange at its upper end and a bushing fitted into the ring against the flange, a securing ring being screwed upon the lower end of the body and provided with a flange for engaging the lower end of the bushing. With this type, the bushing can be removed and a new one put in place but the construction provided causes the throat to be very expensive. It should be further noted that in connection with this type and the one previously discussed. the bushing does not extend to a point flush with the lower end of the ring and therefore a portion of its wearing surface cannot be used as it is overlapped by the securing means. The throat forming the subject matter of this invention is free from the objections noted above and further is sibnliple in construction and strong and dura e. a

The principal object of my invention is to provide a simple and'inexpensive'throat of this character, in which the bushing or lining when worn out or damaged may be quickly and easily replaced by the owner of the bottle capping machine without the use of special tools or machinery.

Another objectof the invention is to so construct this throat that the lowervend of the bushing may terminate flush with the lower end of the body. and the bushing thus provided with a cap-engaging surface which will be of the full depth of the body.

This, invention is illustrated in the accompanying drawing, wherein Figure 1 is a view showing the improved throat in side elevation;

Figure 2 is a vertical sectional view taken along the line 2-2 of Fig. 1.

Figure 3 is a top plan view of the body portion with thebushing removed.

Figure 4: is a sectional View taken along the line 4-4 of Fig. 3.

Figure 5 is a bottom plan view of the assembled body and bushing.

Figure 6 is a perspective view of the bushing.

This improved throat is provided with a body portion 1 which is in the form of a ring and will be formed from a solid piece of metal. This ring or body 1 has its upper end provided with a recess 2 which forms a seat at the upper end of the center passage of the ring or body and the walls of the body have been formed with internal grooves 3 which extend longitudinally of the body and pro ject radially from the center passage. These grooves are V-shaped in end elevation as shown in Figs. 3 and 5 thus providing the body with internal ribs 4 which taper inwardly towards the longitudinal axis of the body. Therefore, when the bushing'or ca crimping means 5 is put in place, the sleeve or bushing will only be engaged at points about its circumference. This will be su'tlicient to provide frictional means to firmly hold the bushing in place but at the same time if the bushing becomes worn. and should crack, it cannot become jammed in the ring or body to such an extent that it cannot be removed. In order to, assist in holding the bushing 5 in place and to limit its movement longitudinally through the body in one direction, the bushing has been provided with an outstanding collar 6 which is of the proper size to fit tightly within the seat 2. This bushing is of the same dept-h as the body or ring 1 and.

therefore when it is driven firmly into place as shown in Fig. 2, its lower end will terminate flush with the lower end face of the body. IVhen the sleeve or bushing becomes worn to such an extent that it cannot be used, it is simply necessary to remove the throat from the bottle capping machine and drive the bushing out through the upper end of the body. The new bushing can then be very easily put in place and the throat replaced in the bottle capping machine. It will thus be seen that with this construction, the sleeve or bushing will be firmly held in place and can be very easily and quickly removed when desired, even though it should become cracked. It will be further noted that since the lower end of the bushing terminates flush with the lower end of the body, the bushing will be provided with an operating face for the entire depth of the body. In other words, when this improved bushing isl'first put into use, the skirt of the bottle cap will engage the extreme lower edge of the inner face of the bushing and the crimping action will take place slightly above that point. When this portion of the bushing wears, the proper adjustment of the plunger mechanism of the bottle capping machine will permit the crimping action to take place at a point a little higher on the inner face of the bushing and thus by successive adjustments, the life of this improved bushing is. prolonged to a considerable extent.

I claim:

1. A bottle capping machine throat comprising a ring having an annular seat at the upper end of itsv center passage and provided with longitudinally extending grooves extending radially from the center passage from the lower end of said ring to the bottom 01 said seat and dividing the wall of the ring into bushing engaging segments, and a cap crimping bushing sleeve fitting into said ring and having its upper end provided with a collar fitting into said seat and covering the upper ends of the grooves.

2. A bottle capping machine throat comprising a body having a center passage and having its walls provided with longitudinally extending V-shaped grooves extending radially from the center passage, the upper end portion of the body being provided with an annular recess forming a circumferentially extending seat about the center passage, and a bottle cap engaging lining fitting snugly into the center opening of said body and having its upper end provided with an outstanding collar fitting into said seat and its: lower end terminating flush with the lower end face of said body, said lining being frictionally held in place.

In testimony whereof I have hereunto afl'lXed my signature.
